In this lesson we are going to learn some special techniques for factoring trinomials. Some of these special factoring techniques will be recognizing the difference of squares, a perfect square trinomial and the difference and sum of cubes. Make sure to factor out the greatest common factor before using any of these special formulas. An important thing to remember here is that there is no formula for the sum of squares. You can see how these formulas work using the examples provided. Some of these special formulas could be used more than once in a particular problem.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
